Application filed January 22, 1914. Serial No. 813.700.

latches and cavels, and has for its objectto provide a device of the character specified, adapted to be attached to the supporting pole of an electric light, for engagement by the flexible suspending member for the lamp to hold the said suspending member from longitudinal movement both in elevated and in lowered position, and wherein the arrangement is such that the lamp will be sup ported in either position, and may be easily lifted and held lifted, and without the possibility of being tampered with by unauthorized persons.

In the drawings :-ll`igure 1 is a side view of a lamp pole with the improvement in place, Fig. 2is a perspective view of the device removed, and Fig. 3 is an enlarged partial perspective view of a portion of the said device.

The present embodiment of the invention is shown in connection with a lamp supporting pole 1, having a laterally extending bracket arm 2 at the top of the pole and braced against the pole by a brace 3. Pulleys 4 and 5 are journaled on the pole and at the end of the arm respectively, and a flexible member G, a chain in the present instance, passes over the pulleys, one end of the chain being connected to the usual ring 7 at the top of the lamp 8. The pulley 4 is journaled in a bracket 9, extending laterally from the pole above the arm 2, while the pulley 5 is journaled in a slot in the end of the arm.

The improvement comprises a cleat consisting` of a body 10 and extensions 11 and .45 12 respectively from the ends of the body,

the said extensions curving outwardly and upwardly, and each being pointed and rounded as shown. A staple 13 is secured to the body 10 of the cleat near the lower end thereof and the cleat is provided with trans verse openings 14, one of which is shown below the staple for receiving securing means 14a to attach the cleat to a pole. A hasp 15 is connected with one of the arms of the staple by means of an opening 16 in one end of the hasp through which the arm of the staple passes, and the said end of the hasp is o'fl'set laterally toward the body of the cleat. The hasp is provided at the opposite end with a longitudinally extending slot 17, which is adapted to fit over a second staple of peculiar construction. rlhe said staple comprises a body 1S and arms 19 and 20 respectively, the arms being secured to the body of the cleat in any desired or usual manner, and the body of the staple is provided with a downward extension 2l at its junction with the arm 20, the said extension being formed by doubling the material of the staple backward upon the body. The body 18 of the staple is also provided with an annular reduction or groove 22 near its junction with the arm 19, and an S-shaped link is connected with the arm 20 of the staple. The said link comprises a large loop 23 and a small loop 241i, the link being formed by bending a single strip of rod or wire upon itself to form the loops or eyes.

The supporting chain 6 of the lamp is provided with a ring` 25 at the end remote from the lamp, and the said ring is engaged with the staple 18-l9-20, the ring being of a size to slip over the entire staple, that is, to inclosel both arms 19 and 20 of the staple. The position of the ring 25 is indicated in dotted lines in Fig. 2, and it will be noted that the said ring is behind the hasp, and that the link 23-24 engages the arm 20 of the lastnamcd staple outside the hasp.

A flexible member 2G as 'l'or instance, a chain, has one end connected with the loop or eye 2li of the link, and the other end with the staple 13, and the said flexible member is of su'llicient length to permit a portion thereof to hang below the said staple.

It will be noticed that the loop or eye 23 of the link 23-2-1 is an open loop or eye, the end of the rod or wire from which the link is formed being spaced from the body thereof to permit the link to be disengaged from the body of the staple 1819-20, when the said open space is brought into register with the groove 22,

To lower the lamp it is necessary to disengage the ring 25 from the staple 1819- 20, and the ring is disengaged in the following manner z-The link 2324 is first released, after which the hasp may be swung out, and the ring may be released from the staple, by swinging the upper part thereof outwardly and downwardly over the body to release the lower pari; of the ring from the extension 2l of the hasp. The lamp is now lowered and after it has heen properly attended to, it is lifted and the procedure is reversed.

The ring 25 is first passed over the extension 2l after which it is swung upwardly until it is in the dotted line position of Fig. 2. The hasp is new engaged with the staple,

and it will loe noted that the slot 17 is of' sutlicient length to permit the extension 21 of the hasp to pass through the same. After the hasp hasheen engaged with the staple, the loop or eve Q3 of the link is engaged with the stanle` thus looking the arts inV ,l 9 a p nisn, namely, the upper staple and thev linlr Zet for preventing disengagement of the ring.

We claim:-

l. A 'device ot the Character specified,

Comprising a cleat, a staple connected with the cleat at the upper end thereof, said staple comprising a body approximately parallel with the adyacent face of the cleat 'and extending longitndinallyT thereof, and

arms approximately perpendicular to the said face, the staple being adapted for en-' gagement by a ring, said staple having an extension at the lower end of the body to prevent disengagement of the ring, a hasp .l piveted to the staple near its lower end and having a slot -for permitting the passage of the staple, and a lock for eoperating vith the staple to prevent disengagement of the hasp. 45

2. A device of the character speeied, comprising a support having at one end a staple and at the other a hasp, the hasp heing' pivoted to the support and having an opening extending longitudinally thereof for permitting the passage of the staple, said staple being adapted for engagement hy ring and Comprising` a body and arms, and leek for engaging the staple outside oi the hasp to prevent disengagement thereof, said lock comprising an open loop, the body of the staple having an annular reduction and the opening of the loop beingV adapted to receive the reduction. y

3. i device of the eharaeter specified, comprising a support having' at one end a staple and at the other a hasp, the hasp being .pivoted to the support and having an opening for permitting the passage of the staple, the staple having an extension at the 6.5 side adjacent to the hasp and having an annular reduction, and a loop having an opening fitting the reduction and forming a look te prevent disengagement of the liasp.
